Oct 2004 Dual G5 2 Ghz to 10.3.7
I installed the 10.3.7 update in my dual 2 Ghz G5
Summary : Everything seems noticably faster, snappier.
Initially : After the upgrade, I hot-restarted and got a beachball for a lot
longer than usual and noted that the usual icons along the top of the finder scrawled individually from right to left across the screen and then the OS loaded - this only happened once.
Mail toook a long time to start up.
I then repaired permissions without anything notable appearing in the list.
I then ran Onyx, cleared out the caches, ran all the scripts etc and shut down the G5.
After a cold restart it booted in about 30 seconds, everything ran a lot faster - including Mail which now seems to open in a second or two. Safari is noticably faster.
Curiously, my mouse scrolls much faster in Firefox than in Safari.
None of my 3rd. party apps have been affected.
The only casualty was XBench which crashed half way through the test (latest version). On a second run it showed a 200 score against a 212 score in 10.3.4 but the whole OS "seems" faster in 10.3.7
Obviously some people installing 10.3.7 have not repaired permissions and "cold started" their Macs after the upgrade or followed the usual maintenance procedures. Macs are like pretty ladies - they need a little attention.
I seem to have a faster G5 tonight than I had this morning.
I'm happy.
